DETAILED DESCRIPTION OF THE INVENTION

Referring now to FIG. 1, an exploded perspective view of a multi-function shoe structure in accordance with a preferred embodiment of the present invention is illustrated. In the preferred embodiment, the multi-function shoe generally includes a flexible sock body designated numeral 10, a sole body designated numeral 20, a first connector designated numeral 30, and a second connector designated numeral 40. The first connector 30 is mounted on an upper surface of the sole body 20, and the second connector 40 is mounted on a bottom surface of the flexible sock body 10. The first connector 30 and the second connector 40 are preferably selected from a pair of Velcro-type fasteners (magic tapes) or other equivalent separable fasteners. Moreover, the sole body 20 is preferably selected from the group consisting of a thinner sole with a first predetermined thickness, a medium sole with a second predetermined thickness greater than the first predetermined thickness, and a thicker sole with a third predetermined thickness greater than the first and second predetermined thickness, wherein the thicker sole has a wear proof effect better than that of the thinner sole and the medium sole.

Turning now to FIG. 2, an assembled cross-sectional view illustrating the multi-function shoe in accordance with the preferred embodiment of the present invention is illustrated. Constructions of the flexible sock body 10 and the sole body 20 shall be described in detail with reference to FIGS. 1 and 2. The flexible sock body 10 is preferably constructed from a traditional sock structure which includes a foot portion 12, a leg portion 14 extended from an end of the foot portion 12, and an inner space 16 defining inside the flexible sock body 10 in an expanded state for accommodating a foot of a user. The sole body 20 is made of at least one plastic material such as polyurethane (PU), ethylene/vinyl acetate (EVA), or the like. The upper surface of the sole body 20 is corresponding to the bottom surface of the flexible sock body 10. The sole body 20 and the flexible sock body 10 can be combined into a single member by the first connector 30 and the second connector 40.

Turning now to FIG. 3, an assembled cross-sectional view illustrating the multi-function shoe used for foot wearing in accordance with the preferred embodiment of the present invention is illustrated. A user can insert his/her foot 90 into the inner space 16 of the flexible sock body 10 until a toe 92 of the foot 90 of the user is received in the foot portion 12 of the flexible sock body 10 while a heel 94 of the foot 90 of the user is positioned below the leg portion 14 of the flexible sock body 10.

In accordance with another aspect of the present invention, the leg portion 12 of the flexible sock body 10 can be selectively omitted or suitably adjusted the length thereof.

When the user wears the multi-function shoe of the present invention in his/her foot 90 for walking or sporting, the flexible sock body 10 accommodates and protects the foot 90 of the user to provide a good warm-keeping effect. Furthermore, due to the sole body 20 is made of plastic materials, the sole body 20 can provide a good skidproof effect when the sole body 20 is in contact with the ground or the floor. Thereby, the present invention can satisfy needs for the warm-keeping effect and the skidproof effect while providing a wearing comfort and preventing the flexible sock body 10 from being released from the foot 90 for increasing the practicability of the multi-function shoe of the present invention.

Turning now to FIG. 4, another assembled cross-sectional view illustrating the multi-function shoe with a sole body 20 selected from a thinner sole used for foot wearing and further inserting into a traditional shoe 50 in accordance with the preferred embodiment of the present invention is illustrated. The flexible sock body 10 is connected to the sole body 20 selected from the thinner sole used as a pad of the flexible sock body 10 so that a sock-and-sole combination of the flexible sock body 10 and the sole body 20 can be inserted into the traditional shoe 50 for providing another type of practicability.

After taking off the traditional shoe 50, the flexible sock body 10 can be detached from the sole body 20 selected from the thinner sole, and further be attached to a sole body 20 selected from the medium sole and thicker than the thinner sole for being used as an indoor type shoe. Alternatively, the flexible sock body 10 can be attached to the sole body 20 selected from the thicker sole thicker than the medium sole for being used as an outdoor type shoe.

For the purpose of convenient carrying the sole body 20, the sole body 20 should be coiled in advance. Furthermore, due to the sole body 20 selected from the thicker sole is difficult to be coiled, the present invention provides a design for overcome the problem.

Turning now to FIG. 5 and 6, a side schematic view illustrating a sole body 20 of a multi-function shoe selected from a thicker sole in accordance with the other preferred embodiment of the present invention is illustrated. The sole body 20 selected from the thicker sole has an upper surface provided with the first connector 30, and a bottom surface provided with a plurality of grooves 22 for increasing the flexibility of the sole body 20 so that the sole body 20 can be coiled into a coiled state as a portable unit to decrease its volume for convenient carrying.
